The total also saw drastic movement. It had plummeted from 45.5 to 41 as of Wednesday afternoon.

Veteran backup Byron Leftwich will get the start for the Steelers. Leftwich replaced Roethlisberger in the second half of the Steelers' overtime win over the Kansas City Chiefs on Monday, completing 9-of-18 passed for 84 yards, with no touchdowns and no interceptions.

In more quarterback injury news, the Philadelphia Eagles are expected to start rookie Nick Foles in place of the concussed Michael Vick at the Washington Redskins on Sunday. Foles took the first-team snaps during Wednesday practice, although Vick has not been ruled out.

The Eagles were 3.5-point road dogs as of Wednesday.

In San Francisco, 49ers starter Alex Smith was on the mend from a concussion suffered Sunday against the St. Louis Rams. Coach Jim Harbaugh told the media Smith's symptoms were improving, but Smith is considered questionable to start Monday against the Chicago Bears, who also are dealing with concussion issues to their quarterback, Jay Cutler.

If Smith can't go, backup Colin Kaepernick will get the nod for the 49ers.

Cutler suffered a concussion in a loss to the Houston Texans, but coach Lovie Smith told reporters that his starter was improving. Cutler does have a history of concussions, and backup Jason Campbell will get the first-team reps in practice this week until Cutler is cleared.

With both quarterbacks questionable, most Vegas sports books had the game off the board as of Wednesday afternoon.
